Fatigue crack paths in cast Inconel 713LC with and without Al diffusion coating were studied under various loading and temperature conditions. Both coated and uncoated specimens were fatigued under symmetric bending, symmetric torsion and in-phase bending-torsion loading at room temperature and under a fully reversed push-pull straining at 800 °C. Optical and scanning electron microscopy were used to study fracture surfaces and polished sections of the gauge segments cut parallel to the specimen axis. The image analysis software was employed to determine the percentage of carbides on both the fracture surfaces and etched specimen sections.
